STRUCT IWL_LQ_STA_RS_FW(9)

💅 struct iwl_lq_sta_rs_fw(9) — rate and related statistics for RS in FW

okay bestie, welcome to the Kernel API Manual entry for struct iwl_lq_sta_rs_fw ✨ this is the little struct that holds all the rate-and-friends stats for RS living in FW — and honestly? it's giving "small but crucial" 🎀

🌸 NAME

struct iwl_lq_sta_rs_fw — rate and related statistics for RS in FW 💖

---

✨ SYNOPSIS

struct iwl_lq_sta_rs_fw {
    u32 last_rate_n_flags;
    struct lq_sta_pers_rs_fw {
      u32 sta_id;
  #ifdef CONFIG_MAC80211_DEBUGFS;
      u32 dbg_fixed_rate;
      u16 dbg_agg_frame_count_lim;
  #endif;
      u8 chains;
      s8 chain_signal[IEEE80211_MAX_CHAINS];
      s8 last_rssi;
      struct iwl_mvm *drv;
    } pers;
 };

no cap, that nested pers struct is the whole personality of this thing 🫶

🦋 Members

• last_rate_n_flags — the last rate that FW reported back to you, periodt 📡
• pers — the persistent fields, aka the stuff that sticks around 💾
• pers.sta_id — the id of the station, iconic little identifier 👑
• pers.dbg_fixed_rate — debug-only: if it's not 0, use a fixed rate. fr fr, only for debug 🙈
• pers.dbg_agg_frame_count_lim — debug-only: the max number of frames in an A-MPDU 🔥
• pers.chains — a bitmask of the chains reported in chain_signal 🧚
• pers.chain_signal — per-chain signal strength, one for each chain, so thoughtful 🌈
• pers.last_rssi — the last rssi that got reported 📶
• pers.drv — a pointer back to the driver data, a little boomerang moment 🪃

heads up: dbg_fixed_rate and dbg_agg_frame_count_lim are chill but they're debug fields — they live behind CONFIG_MAC80211_DEBUGFS, so don't count on them being there 💀
